Here is some info for your drivetrain questions. http://chevyc60.com/index.htm
Now I know it says C60, but most interchanges with your 50. With that out of the way, first thing I would do is to pull all the fuses out of that panel. Keep track of where they go!! then get some contact cleaner and scrub all the fuse mounts. As far as the headlights, I would hit the switch with the contact cleaner to see if that helps and do the same to the headlight connections. A cheap multimeter is your friend too!!
